AI-first code editor. Multi-model, tab-completion native.

Fork of VS Code with deep model integration — multi-line tab completion, agent mode, chat with codebase context. Strong for fast iteration on existing repos.

AI pair programmer in your editor — completions, chat, and agents.

The original in-editor AI coding assistant, offering multi-line completions, chat with codebase context, agent mode, and a cloud coding agent that opens pull requests. Runs across VS Code, JetBrains, Visual Studio, the CLI, and GitHub.com. A free tier covers light use; paid tiers add premium models and more allowance.

Cascade agent + IDE. Codeium's developer surface.

Agent-first IDE that pairs autocomplete with Cascade, a planning-then-acting agent. Strong terminal integration; good when the diff spans many files.

AI code review and test generation across IDE, PRs, and CLI.

Qodo (formerly CodiumAI) is a code-quality platform that runs AI review on pull requests, generates tests, and assists inside the editor. Its multi-agent reviewer pulls context from the codebase and PR history across GitHub, GitLab, Bitbucket, and Azure DevOps, with VS Code and JetBrains plugins plus a CLI so issues surface before merge.
